６．３ Shock-less function
In order to preuent a lifted cargo from swinging, it allows the crane to make a
smooth stop when operated through radio remote control.
When making the crane a sudden stop, actuate the “selector switch” controlling
opposite function while the shock-less is functioning.
(Do not pull the speed lever during this operation.)
In order to inactivate the shock-less function, turn ON the “hook winding-down”
switch with the “Mode switch” depressed.
６．４ Interlocking balance control function
This is the function that controls the movement of lever and the engine speed for
every combination of interlocking operation through radio remote control.
Examples listed below are not a fault:
When controlled through radio remote control device, the movement
of lever differs each time of operation or the control lever will not be
shifted to its maximum.
When operation is switched from interlocking to independent, control
speed may become slower than that of the independent operation in itself.
Stop the radio remote control operation once and go back to independent
operation again to return it to the original control speed.
This is a measure preventing its operating speed from making an abrupt
increase when operation is switched from interlocking to independent.
Following gives a serious influence on performance of interlocking operation:
Unspecified hydraulic pump has been mounted.
The rated speed of hydraulic pump has not been set as specified.
Any of control levers has been altered.
Hooking system has been changed.
